This makes it possible to import header from the kernel more easily, e.g.:
cd $path_to_linux_repo
make headers_install
rsync -a --exclude .\* usr/include/linux/can* $path_to_can_utils/include/linux
[mkl: also move isotp.h although Uwe skipped it as it is not
part of the upstream kernel; adapt commit log accordingly]

This patch changes the include from the socketcan folder to the linux folder:
-#include <socketcan/can.h>
+#include <linux/can.h>
so that the socketcan folder can be eliminated in a later patch.

This header doesn't exist in the Linux tree and it's unused by can-utils,
so drop it.

These seem to have never been used. They entered can-utils in commit
77de10356f (include: import kernel header files into tree) and already
back then only consisted in an #include of a non-existing file.

Usually the received CAN frames can be processed/routed as much as 'max_hops'
times (which is given at module load time of the can-gw module).
Introduce a new configuration option ( -l <hops> ) to reduce the number of
possible hops for a specific gateway rule to a value smaller then max_hops.

Added new option '-i' for can-gw rules to allow to route CAN frames back to the
originating/incoming CAN interface (which is disabled by default).
CAN frames that are deleted due to the violation of the max_hops limit are now
printed when displaying the configured rules with 'cangw -L'.

There has been a change with __kernel_sa_family_t in Linux 3.1 which was not
adopted in this update so far to be backward compatible with old environments.
